Osomatsu-kun Hachamecha Gekijou (おそ松くん はちゃめちゃ劇場) is a 1988 action game by Sega for the Sega Mega Drive tying into the Osomatsu-kun media franchise in Japan, which at the time saw a revival in the form of an anime series stared the same year by Studio Pierrot and is the first Mega Drive game that never left outside Japan. It is one of the few Mega Drive games to never receive full support for TMSS, meaning it will only work on most Model 1 Mega Drives.

It is partially unknown who has made the game, since there is no credits in any part of it.
